If the storm shifted toward Houston, NASA would evacuate the space centre, which oversees the shuttle during flight, and set up an emergency command post at KSC in Florida. Endeavor is scheduled to touch down in Florida at 1232 EDT (1632 GMT) on Tuesday, but the back-up landing site at Edwards Air Force Base in California will be available if needed, Shannon said.
